Romans 12:1-8I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service. And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith. For as we have many members in one body, but all the members do not have the same function, so we, being many, are one body in Christ, and individually members of one another. Having then gifts differing according to the grace that is given to us, let us use them: if prophecy, let us prophesy in proportion to our faith; or ministry, let us use it in our ministering; he who teaches, in teaching; he who exhorts, in exhortation; he who gives, with liberality; he who leads, with diligence; he who shows mercy, with cheerfulness.

Only by God's mercy can be present ourselves as living sacrifices. We must choose to let Him perfect that which He gives to each by His grace. We each have a measure of faith. But we are many members each unique and special to Him. Each with gifts that will honor Him and be used by Him to bring harmony in the body. Choose to present yourself to God, Choose to let Him use the gift in you. Choose to be a part of the body pleasing to the Lord.
